I'd never use anything on my new Macans body, other than a hand wash. But I have a gas powered 3400psi pressure washer with many tips for various strengths of spray. The brake dust on my silver wheels is bad and I can't reach in there to clean internally. Would it be safe to use my pressure cleaner at a wide angle pressure to get them nice and clean? I can put some Mr.Pink in the soap dispenser on it too for apply foam prior to rinse. Thoughts?
